Electron Gun - English Definition & Meaning

Definition

An electron gun is a component in devices like old TVs or monitors that shoots a beam of electrons onto a screen to create an image. Think of it like a tiny, super-precise squirt gun, but instead of water, it fires electrons. These electrons hit a special coating on the screen, making it glow. It's a key part of how cathode ray tubes (CRTs) work, which are now mostly replaced by newer technologies like LCD and LED screens. Imagine it as the projector in an old movie theater, but for tiny particles.

Etymology

The term 'electron' comes from the Greek word 'ēlektron,' meaning amber, because static electricity was first observed by rubbing amber. 'Gun' is used metaphorically to describe the directed emission of a beam. The combination describes precisely what it does: shoots electrons.
